Diod laser terkunci mod nadi berlanggar 160 GHz (CPM-LD) telah distabilkan dengan suntikan kereta api denyut laser induk stabil diulang pada frekuensi subharmonik ke-16 (9.873 GHz) daripada frekuensi pengunci mod CPM-LD. Pengukuran kamera stik syncroscan mendedahkan kereta api nadi yang jelas dengan kekerapan ulangan 16 kali bagi kereta api nadi laser induk untuk output CPM-LD yang stabil, menunjukkan bahawa output CPM-LD telah disegerakkan dengan laser induk dan jitter pemasaan juga dikurangkan. Jitter pemasaan CPM-LD yang distabilkan telah dinilai secara kuantitatif oleh teknik penukaran ke bawah semua optik menggunakan ketaklinearan gentian optik. Teknik ini mudah dan mempunyai lebar jalur yang lebih luas berbanding dengan teknik konvensional, membolehkan anda mengukur dengan tepat hingar fasa kereta api nadi optik ultrafast apabila kekerapan ulangannya melebihi 100 GHz. Pengukuran spektrum kuasa elektrik menunjukkan bahawa frekuensi penguncian mod CPM-LD betul-betul dikunci oleh suntikan kereta api nadi laser induk dan jitter pemasaan berkurangan apabila kuasa suntikan meningkat. Jitter pemasaan telah dikurangkan daripada 2.2 ps dalam operasi larian bebas kepada 0.26 ps pada kuasa suntikan 57 mW, setanding dengan laser induk (0.21 ps).

Abstract: A 160 GHz colliding-pulse mode-locked laser diode (CPM-LD) was stabilized by injection of a stable master laser pulse train repeated at a 16th-subharmonic-frequency (9.873 GHz) of the CPM-LD's mode-locking frequency. Synchroscan steak camera measurements revealed a clear pulse train with 16-times repetition frequency of the master laser pulse train for the stabilized CPM-LD output, indicating that CPM-LD output was synchronized to the master laser and that the timing jitter was also reduced. The timing jitter of the stabilized CPM-LD was quantitatively evaluated by an all-optical down converting technique using the nonlinearity of optical fiber. This technique is simple and has a wider bandwidth in comparison to a conventional technique, making it possible to accurately measure the phase noise of ultrafast optical pulse train when its repetition frequency exceeds 100 GHz. The electrical power spectra measurements indicated that the CPM-LD's mode-locking frequency was exactly locked by the injection of the master laser pulse train and that the timing jitter decreased as the injection power increased. The timing jitter was reduced from 2.2 ps in free running operation to 0.26 ps at an injection power of 57 mW, comparable to that of the master laser (0.21 ps).
